Fabric care compositions comprising cellulose binding domains

Abstract

The present invention relates to fabric care compositions comprising one or more amino acid sequence(s) comprising a Cellulose Binding Domain for providing fabric care. In a further embodiment, the present invention relates to fabric care compositions wherein the amino acid sequence comprising one or more cellulose binding domains is linked to a softening protein.

1. A fabric softening protein hybrid comprising an amino acid sequence comprising a cellulose binding domain linked to a fabric softening protein;
 wherein said fabric softening protein is linked to said amino acid sequence comprising a cellulose binding domain, via a non-amino acid linking region;  
 wherein the cellulose binding domain is selected from the group consisting of CBD Cellulozome from  Clostridium cellulovorans , CBD E3 from  Thermonospora fusca , CBD-dimer from  Clostridium stecorarium  XynA, CBD from  Bacillus agaradherens , and combinations thereof;  
 further wherein said non-amino linking region is a polymer selected from the group consisting of polyethylene glycol derivatives, nucleophilic polyethylene glycol derivatives, carboxyl polyethylene glycol derivatives, electrophilically activated polyethylene glycol derivatives, sulfhydryl-selective polyethylene glycol derivatives, heterofunctional polyethylene glycol derivatives, biotin polyethylene glycol derivatives, vinyl polyethylene glycol derivatives, silane polyethylene glycol derivatives, phospholipid polyethylene glycol derivatives, 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide, N-ethyl-5-phenylisoaxolium-3-sulphonate, 1-cyclohexyl-3(2-morpholinoethyl) carbodide metho-p-toluene sulphonate, N-ethoxycarbonyl-2-ethoxy 1,2, dihydroquinoline, glutaraldehyde and mixtures thereof; and  
 further wherein said fabric softening protein is selected from the group consisting of: hydrolases, lyases, oxidoreductases, ligases, transferases, isomerases, cellulases, xylanases, mannanases, arabinofuranosidases, acetylesterases, chitinases, polyamino acid resin solutions, C 18  alkyl quaternary wheat protein derivatives and combinations thereof.  
 
     
     
       2. A fabric care composition comprising the fabric softening protein hybrid according to  claim 1 . 
     
     
       3. A fabric softening protein hybrid according to  claim 1  wherein the amino acid sequence comprising a cellulose binding domain is selected from CBD Cellulozome from  Clostridium cellulovorans.    
     
     
       4. A fabric care composition according to  claim 2  further comprising another fabric care ingredient. 
     
     
       5. A fabric care composition according to  claim 2  further comprising a fabric care ingredient wherein said fabric care ingredient is selected from the group consisting of a cationic surfactant comprising two long alkyl chain lengths, a clay, a transferase and/or mixtures thereof. 
     
     
       6. A method comprising the step of contacting a fabric with a fabric care composition according to  claim 2  to provide fabric softness, anti-wrinkle properties, anti-bobbling properties, anti-shrinkage properties, static control, colour appearance and fabric anti-wear properties and to provide, refurbish or restore tensile strength.
